Hansen's Natural Sodas have been a natural soda brand in Southern California for the past 30 years.[4] In the 1930s, Hubert Hansen and his three sons began selling juice to film studios and retailers in Southern California under the Hansen's name. In the 1970s, Tim Hansen (the grandson of Hubert) developed and marketed a variety of sodas and juices, also under the Hansen's label.[5]

The company became Hansen's Juices, and later The Fresh Juice Company of California. The plant that was opened in Los Angeles in 1946 was used until operations were moved to a new plant in Azusa, California in 1993. The company filed for bankruptcy in 1988, and was acquired by the California CoPackers Corporation and renamed Hansen Natural Company. In 1998, the company moved from Anaheim, California to Corona, California. On January 5, 2012, shareholders agreed to change the name of the company from Hansen's Natural to Monster Beverage Corporation, under the new ticker MNST. Shareholders also approved an increase in the number of authorized shares of common stock to 240,000,000 shares from 120,000,000 shares.[6]

Hansen's Juice Blast line of children's juice drinks was launched in conjunction with Costco and sold in Costco stores. Hansen also has a Juice Slam line of children's juice drinks. Both lines are sold in 6.75-ounce boxes.

In May 2001, Hansen's acquired the Junior Juice beverage business.[9] Hansen's Junior Juice is 100% juice, sold in 4.23-ounce cartons and targeted at toddlers and preschoolers. Certain flavors of Junior Juice have calcium added and all flavors contain 100% of the daily recommended allowance of Vitamin C. The brand was introduced in 1991 by McCain Foods,[10] and sold to the Pasco Beverage Group in 2000[11] before being sold again, to Hansen's. Hansen's replaced the original four mascots, Uncle Froggy, Emily the Mouse, Ronald Rabbit, and Nick the Fox,[12] with Clifford the Big Red Dog.

In July 2008, Hansen's introduced Hansen's Organic Junior Water, in 4.23-ounce packages aimed at children between two and six years old. The Hansen's Organic Junior Water line of flavored water contains 100% of the daily recommended allowance of Vitamin C and thirty calories per serving. Also in 2008, organic Junior Water was introduced. Hansen's later introduced Coconut Water Twist, containing coconut water,[4] and Garden Twist, a combination of fruits and vegetables, which is the only Junior Juice variant to be sold in bottles.[4]

Smoothies, Rumba Energy Juice,Energade, and Energy Formula, are minor products. Hansen's owns Blue Sky Beverage Company, which manufactures several soft drinks. Hansen's produces the Monster, Lost, and Rumbaenergy drinks, which were previously distributed in the United States by Anheuser Busch.[13] On November 10, 2008, distribution of the Monster Energy and Monster Java products was turned over to Coca-Cola Enterprises.

In 2006, Hansen's introduced a line of iced teas in 16-ounce PET bottles. Some varieties were sweetened with cane sugar and some were unsweetened. Flavors included Lemon Mint, Pomegranate, Ginger, and Tangerine. There were also three flavors of diet green tea soda: Lemon Mint, Ginger and Tangerine. Each bottle of tea contained 75 mg of Epigallocatechin gallate. Hansen's also made tea bags.

In April 2008, the FDA ruled products containing high-fructose corn syrup could not be labeled "natural".[14] Shortly after, Hansen's Natural Corporation announced they had begun using cane sugar instead.[15]

In September 2009, Hansen brand Monster Energy sent a cease and desist letter to Rock Art Brewery, demanding the microbrewery stop selling its new Vermonster beer, drop its pursuit of a federal trademark for the name, and pay Hansen's lawyer fees. This resulted in a boycott of all Hansen products by some Vermont retailers.[16]
